There is no possible way, the closest you can get to this is using generic T-51b over the BoS T-51b or using Honest Heart's survivalist armor. Other than that, you cannot do this.
Aw, that svcks. Hopefully in LR there will be a machine that defactionizes your armour, that would be nice to have.
Also the reg. T51b has a ton of rust on the chestplate
